Combinations of Resistors and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Electric Resistance. Combinations of Resistors. you can access all the lessons from this tutorial below.
In this Physics tutorial, you will learn:
Does electricity flow freely through a conductor? Do you think all electrical energy produced by the source converts into the desired form? Why?
What is the main purpose of an electric heater? What kind of energy transformations take place when we turn it on? Is there any undesired form of energy produced during the operation of an electric heater?
Now, answer the above questions considering a light bulb. What conclusions do you draw regarding the undesired form of energy in this case? Is it the same as for electric heater? Why?
In this tutorial, you will learn about a phenomenon known as electrical resistance. We encounter it everywhere, every time we turn on an electrical appliance. Therefore, this tutorial has a great importance on the practical aspect.
